As more people have embraced natural hair care, shampoo has gotten a bad reputation. This is due to its surfactant called Sodium Lauryl Sulfate (SLS) which can cause dryness. Or you may find harmful chemicals like synthetic coconut oil, Cocamide DEA in shampoo.
As a result, some naturals have taken up co-washing. Let us investigate both methods of hair cleansing and their effectiveness.
Shampoo is designed to remove dirt and oil, so the process of shampooing can make hair feel dry. This causes it to be susceptible to breakage. Dryness, however, can be remedied with application of a moisturizing conditioner after shampooing. There are also SLS-free shampoos that are gentler alternatives to Sulfate-laden shampoos.
Co-washing can remove some dirt and oil, but is ineffective at removing build up. Conditioner can also cling to the hair and has more oily materials which can attract more pollen, dust, and dirt. If left unremoved, this build up is harmful to your hair and scalp (Reed, Camille E. 2013, February 17 “5 Hair Blogger Falsehoods” [Blog post] retrieved from http://www.afrobella.com).
Overall, to optimize hair growth, the scalp needs to be free of clogged follicles. Co-washing from time to time is okay as long it's not the only cleansing method utilized. Conditioner has its place to soften your hair and add protein - not to remove build up. You may be avoiding shampoo, but do consider an SLS-Free shampoo like our Rhassoul Clay Shampoo & Body Bar that will actually cleanse your hair and scalp thoroughly.
